Abstract

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a global pandemic. The virus commonly affects the respiratory system, and a typical manifestation is viral pneumonia, occasionally leading to acute respiratory distress syndrome (ARDS) and death. However, emerging evidence suggests involvement of the cardiovascular system also; the proposed mechanisms include direct myocardial damage, plaque rupture secondary to inflammation, and right heart strain secondary to ARDS. Myocarditis is the primary cardiac manifestation reported in multiple case reports and small series. Cardiac magnetic resonance (CMR) is the most accurate cardiovascular imaging technique for diagnosing myocarditis and differentiating it from other etiologies. In this review, we summarize the pathophysiology, clinical features, and CMR imaging of COVID-19 myocarditis.
